BANDING- IVIACHlNE.

SPECIFICATION forming part of Letters Patent No. 391,728, dated October 23, 1888.

Application filed January 12, 1588. Serial No. 260,595. (No model.)

To aZZ whom it may concern:

Beit known that I, GEORGE WATCHERS, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in 5 Banding-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide means by which to mark loop-bands employed in spinning and other machines while the said bands or the material forming or to form the bandsis distended, the said bands being marked at a defined distance from their loop end, and r preferably while the band is distended between two points, and the devices for making and marking the loop-bands are so made as to mark the bands under like conditions of tension, so that a series of said bands used in a frame and drawn to the mark and tied may be brought to the same tension. If the tension of a band when tied is too little, the yarn twisted by the spindle rotated by the Said band is slack twisted. So in the effort to avoid slack'twisted :2 5 yarn the operators tie the bands unnecessarily taut, so that it is estimated by good authority that at least ten per cent. of the power consumed in driving spindles is due solely to tootight banding, and when the bands are too taut the wear of the spindles and bearings is excessive and very injurious, necessitating frequent renewal both of the spindles and bearings and the bands.

The essential feature of my invention is a means for marking the bands at a defined dis tance from the loop end; and my invention consists in the combination, with a hook or holder for the loop end of the band, of a marker whereby successive bands when distended may 0 be marked at a uniform distance from their loop ends in order that the marked band may be drawn up to the mark to be tied, leaving the band at the established tension.

Hy invention is herein shown as embodied 5 in connection with the class of machine described in United States Patent No. 121,031, dated November 14, 1871, to which reference may be had.

Figure 1 in side elevation represents a loopbanding machine embodying my invention. Fig. 2 is a top or plan view of Fig. 1. Fig. 3

is an enlarged sectional detail taken longitudinally through the machine, showing some of the parts by dotted and full lines in different positions, the carriage occupying, however, a

different position from that shown in Figs. 1

and 2, it being in its extreme backward or normal position. Fig. 4: shows a loop-band marked in accordance with my invention. Fig. 5 is a modification, to be referred to. Fig. 6 shows parts ofa band marked near its open end, the band being broken out to save space upon the drawings; and Fig. 7 shows a band in the process of being tied about a spindle whirl and drum.

Referring to the drawings,the bed-plate A, supported upon suitable legs, has at its opposite ends and near its center suitable uprights to form bearings for parts to be described. This bed-plate, its bearings, the shaft B, having the fast pulley D and loose pulley O, the revolving head WV, containing the pinions Z) d d, the latter being 011 the shanks of the twisting-hooks G G, the guide-rods U U, the slide or block J,havinga hook,H,and provided with projections K K,the shipper-rod S,havlng attached to it the belt-guide E, the shipper-handle F, the arm L, fast upon the shipper-rod, the rod T, its attached stop I, to engage and prevent the rotation of the revolving head W while the two halves of the band are being first twisted preparatory to being doubled together, the arm L, attached to the said rod T,the pulley P, and the weight Q are all substantially the same as in the said patent, wherein like devices are designated by like letters.

The weight Q is connected to the rear side of the slide J by a cord, as a, the weight normally keeping the hubs a. of the slide against the springs a", resting against the collars O, secured in adjustable manner to the guiderods U.

The shipper-rod S is free to both slide and oscillate to a limited extent. This rod has attached to it near one end a collar, b, and is extended through the spring R, the spring normally acting to move the rod in the direction of the arrow 2 near it in Fig. 1,the said spring moving the rod in that direction to shift the usual driving-belt from the fast to the loose pulley whenever the toe 3 (see Fig. 1) of the shipper-handle F is disengaged from the holding-plate c,fast to the bed-plate A, the said toe being removed from the said holding-plate by an oscillatory movement of the said shipperrod S through the action against the arm L of the beveled projection K,attached to the slide J,when the slide arrives at the extreme of its movement to the right,(viewing thedrawings,) that taking place while the said slide is being moved forward and the twohalves of the band are being doubled together. The for ward ends of the guide-rods U are supported in the uprights 0 and their rear ends in the uprights o portions of the said uprights below their upper ends also forming bearings for the rods S and T. The slide J has a, depending portion, 4:,to which is pivoted at 5 a loop-like catch, 0.

The bed A ofthe machine has erected upon it a hollow post or upright, f, which receives a rod, provided, as herein shown, above the post with projections 6, which receive upon them a marker-holder, g, the said markerholder receiving a crayon, ehal k, or other suitable marking substance, as 7, which, when brought against the band, will mark the same. The lower end of this rod g has an arm, 5 which is extended outwardly through the said postf and has connected to it loosely a link, 9 which is in turnjointed to the short arm ofa lever, gflconnected, as herein shown, by a slot and-pin connection with the slide-bar h, thelever g having connected toit one end of a strong spiral spring, g which is attached to a stud, 8, on the bed-plate, so that the said' spring normally acts to keep the rod, the holder, and a suitable crayon or chalk, 7, together with the lever g, in the'dotted-line positions shown in Fig. 2,0r out of operative position. The slidebar h is extended through and guided by suitable guide-loops, h, screwed one to the bedplate and the other to a plate, 0, attached to the bed-plate. The forward end of the slidebar is turned upward to constitute a hook, as if. (Shown bestin Fig. 3.) The uprights c are herein shown as rising from the plate 0 attached to the bed-plate by suitable screws. The left-hand side of this plate a (see Figs. 2 and 3) has ears which receive a pin or stud, 10, upon which is pivoted a slotted catchlifter, m, the upturned end h of said bar h normally standing in the slot of the said catchlifter, with its end above the top of the said lifter, as shown in Fig. 3 by full lines, except when the said lifter is elevated by the sliding wedge or cam m, to be described. The bed of the machine has also connected to it by a screw, as 12, a spring-like finger, e, which serves as a support for the catch during part of its movement, the said finger extending for ward over the catch-lifter m, its downturned forward end substantially meeting the up turned end it of the bar it.

The hub of the arm L, attached to the shipper-rod S, (see Fig. 2,) is made to enter a notch in the wedge or slide m, so that when the said shipper-rod is moved to the right (viewing the drawings) to shift the belt from the fast upon the loose pulley the hub of the said arm attached to the rod S will carry with it the wedge or slide m, so that its inclined end (see Fig. 3) will act upon the downturned free end of the catclrlifter m and raise it into the dottedline position shown in Fig. 3, in orderthat the said lifter may elevate the free end of the catch 6 then beyond the free end of the finger e and insure that the said catch 6 during the movement of the slide J back to the left will pass upon the rounded front end of the finger e, thus preventing the said catch 6 from catching the end h of the bar.

The drawings, Figs. 1 and 2, by full lines show the parts of the machine in the positions they will occupy just as the carriage has started to go back immediately after the two twisted strands s s of the band are brought together, the marker being at that time operated to mark the bands, as at a In Fig. 3 the catch 6 is in its normal position with the carriage way back, the upper end of the arm lat, attached to the rod T,at such time occupying a position close to the hub a of the slide J and against the inner beveled side of the projection K, the said beveled projection in the backward movement of the slide J by the strain of the weight Q acting upon the said arm 14 to oscillate the shaft T far enough to place the stop I in position to engage the revolving-head W and prevent its rotation, as in the said patent, when the shaft B is again started.

In operation the material to be twisted into a band has its ends secured to the hooks G,projecting from the pinions d, and the central portion of the materialis engaged with the hook H. In this condition, the carriage being back in the position, Fig. 3, the operator engages the handle F, moves the shipper-rod S to the left far enough to place the usual driving-belt upon the fast pulley D, and thereafter the shaft B is rotated,so that the pinion b rotates the pinions d, and the revolving head W being held stationary the hooks g twist each one-half of of the band extended to and about the hook H. As the two halves of the band are twisted independently, the material forming the band is gradually shortened and the slide J is drawn toward the right until the front edge of the projection K meets the arm L and turns the rock-shaft T far enough to release the stop I from the revolving head W. During this first forward movement of the slide J the hooked catch 0 passes just beyond the end of the latch e and drops down upon the lifter m just in front of the upturned end h of the bar IL. As soon as the revolving head W is released, it commences to rotate with the shaft B, and as it rotates it commences to unite the two halves of the band together between the hooks H and G. At the commencement of this doubling operation the band is somewhat slackened and the weight Q draws the slide J back for a slight distance, and in so drawing back the slide the catch 6 engages the upturned end h of the bar h, and through it turns the lever g and link quickly throwing the marker around into the full-line positions, Figs. 1 and 2, to mark the band, holding the marker in such position for all the bands to be applied at a standard and a short space of time while the two halves of at the same tension.
